Aiphone intercom systems are very restricted in what you can and cannot connect. Also the type of functionality you require is determined by the master station that you have. With apartment system VC6M you will be able to configure very specific modules which can be viewed at this site and this is not much.

As the description suggests it is only meant to be a cost effective audio unit. (Video is available in apartment mode with the GT system)

internal damage. take it apart and inspect for damage

For anyone googling this, to take apart the audio technica pro 45 just peel off the sticker on the bottom to remove the three hidden screws. Everything then just slides out the bottom.

1. Remove the NEGATIVE battery cable (to avoid accidently causing vehicle damage due to shorting out electrical circuits)

2. Remove the ash tray

3. Remove the screws securing the center facia panel

4. Remove the center facia panel by gently prying rearward to release clips

5. Remove screws securing audio unit

6. Remove audio unit from the mounting bracket.

7. Installation is the reverse of removal.

plug the deck in.

No it will not. The reason for the word phantom is that it does not affect microphones that don't need it (apart from some types of ribbon mics)

take it apart, wipe up any remaining water and let it air dry for 24hrs. Put it back tgether and see if it works. If it does you're lucky, if not start taking apart your wallet to fix it. HTH.

You can more than likely. Look it up on the internet, there should be a diagram somewhere showing you how to take it apart.

Don't Take It Apart!!! You'll ruin the warranty, you could probably still send it in it the warranty is still active. besides don't take it apart the chip is probably fried,
